LAC TŌYA-KO

Lake Tōya-ko is almost circular. The Tōya-ko Onsen spa is located south of the lake. In 1943, Mount Shōwa Shinzan appeared after a few earthquakes and rose to 402 m. From the parking lot, a cable car takes you to the top of Mount Usu-san (732 m). This small volcano is still active, as in 1977 an eruption damaged the cable car and covered the Tōya-ko spa with over 40 cm of ash and dust. From the top, you can enjoy the view of Mount Yōtei-zan and the lake.
